Abstract:
A weak value amplification (WVA) Corolis vibratory gyroscope (CVG) is provided for measuring angular rate. The WVA CVG includes a vibratory structure that induces a deflection; an optical weak value amplifier that amplifies the deflection as an amplified signal; and a weak value detector to measure the amplified signal to determine the angular rate. Further exemplary embodiments provide first and second plates, a laser, a polarizing filter, a beam-splitter, left and right mirrors, a half-wave plate, a retarder and a detector. The laser emits an emission beam of photons. The polarizing filter polarizes the emission beam. The beam-splitter divides the beam into left and right beams reflected by the left and right mirrors. The retarder imposes a phase difference between the left and right beams. The detector measures the left and right beams.
